Answer:
125
Explanation:
Calculation to determine the demand forecast for year 3 using the double exponential smoothing method
Smoothed forecast for year 3 = (0.3 ×150) + (0.7 ×100) + 10
Smoothed forecast for year 3 = 45+70+10
Smoothed forecast for year 3 =125
Therefore the demand forecast for year 3 using the double exponential smoothing method will be 125
